Acute angle: - correct answersAngles between 0 and 90 degrees
Obtuse angle: - correct answersAngles between 90 and 180 degrees
Right angle: - correct answersAn angle of exactly 90 degrees
A circle is: - correct answersthe set of all points in a plane that are the same distance from a fixed point
(called the center). The distance from the center to any point on the circle is the radius. The diameter is
the largest measurement across a circle.
Triangles: - correct answersthree sides, three interior angles, and always sum to 180 degrees.
Scalene triangle: - correct answershas no equal sides or angles
Isosceles triangle: - correct answershas two equal sides and two equal angles.
Equilateral triangle: - correct answersall three sides are equal as are all three angles. Each equilateral
triangle must be 60 degrees = 180
Quadrilaterals: - correct answershave four sides and four angles
Rectangle: - correct answerseach of the four angles measure 90 degrees and there are two pairs of sides
with equal lengths
Square: - correct answersas four 90 degree angles, and all four of its sides are an equal length

Three-dimensional objects, such as cubes, can be measured in three dimensions: - correct answers-
length, width, height
Three-dimensional objects are also called solids, and the shape of a flattened solid is called a net.
The surface area (SA) of a three-dimensional object can be figured by: - correct answersadding the areas
of all sides.
Surface area is measured in: - correct answerssquare units (m2 of ft2) Volume (V) is the amount of space
that a three-dimensional object takes up. Volume is measures in cubic units (ft3 or mm3)
A rectangular solid: - correct answershas six rectangular sides. A cube is a type of rectangular solid in
which all the sides are squares. Every rectangle solid has a width (w), a length (l), and a height (h). Its
surface area is the sum of the area of each rectangle, and its volume is found by multiplying the width,
length, and height.
Surface area = 2lw + 2hw +2hl
V= wlh
